Putting the lightmeter under the chin makes sense to me because: a) It is incident light what's being measured, and the little sphere is to be located as close as posible to the surface being iluminated (i.e. the face's skin). Putting the lightmeter at the same distance from the light source is crucial as light intensity varies with distance to the source. ...


Lightmeters are superior to in camera metering because they are able to measure the incident light, not just the light reflected off the subject. Reflected light metering is less accurate as the camera/meter has no way of telling the difference between a white cat that is massively underexposed and a black cat that is correctly exposed. With incident ...


In digital photography, the most issues come from the dark portions of the image where sensor noise has the most impact on the quality of the result. Electronic sensors accumulate light, but while they are collecting light, they also collect random noise. To avoid this noise being an issue, a technique known as ETTR or exposure to the right is even used ...


Like you this bothered me as well. Depending on the lens, the exposure was always underexposed to some degree. I use a Sekonic L-758DR, but in the end I don't calibrate using the provided software and tests required. My gear is Nikon. Effectively their camera calibration procedure takes lens transmission loss into account, along with many other variables ...


Disclosure: I'm the guy behind Cine Meter and Cine Meter II, so take what I say with a grain of salt, grin. Do these apps really work, or are they gimmicks? They really work, within the limits of what the built-in camera allows. They may not be able to measure really dim light, for example. Can they get the same information from a scene that a ...
